On-the-go travel humidifiers can help you create a more comfortable sleeping environment. Hotel rooms often have drier air than what you may be used to at home. But the travel humidifier will raise the level of moisture in the room, making it more comfortable. Most travel humidifiers don’t contain filters, which simplifies cleaning. These units often use water from a standard water bottle, simplifying the operation. Some have a built-in LED light that can serve as a nightlight in a hotel room. You may even want a really small size of travel humidifier for use in the car as you’re driving. Such units will be small enough to fit in a cup holder and run from a USB cable.
